If your modem is not a router, look at how your computer is connected to the modem. If your
computer is connected directly from the modem to the PC, then you do not have a router. Your
connection is not being split up, and you do not need to do any Port Forwarding. This is the easiest
setup, but these days a setup like this is usually rare.
If your modem is not a router, but you have your computer connected to a separate router, then you
need to configure Port Forwarding on your router. Refer to 3.40.7 Setting up Port Forwarding on Pg.
93 to set up Port Forwarding.

If your modem is a router, then you need to determine if it is the only router present. If you have
more than one router, then you will need to bypass all but one of them. The first step is determining
whether or not there is a second router present. Follow the cable from your computer. Does it connect
directly into the modem? If this is the case, then you only have one router (the modem). You will need
to configure Port Forwarding on that modem as detailed in 3.40.7 Setting up Port Forwarding on
Pg. 93 .
If your computer is connected to another device between it and the modem, then you need to
determine what kind of device it is. Hubs and Switches do not split up connections like routers do
(they only split up cables), and do not require any Port Forwarding. But if you have a router between
the computer and the modem, this means you have two routers present, and that creates a problem.
You will need to bypass the second router, or you need to turn off the router inside of the modem.
Turning off a router is done by setting the modem to Bridging mode. This cannot be done on all
routers, and to do this you should contact your ISP. Ask them if they can help you set the modem into
Bridging mode. Once the modem is in Bridging mode, you only have one router, and need to set up
Port Forwarding, as detailed in 3.40.7 Setting up Port Forwarding on Pg. 93 .
